/**
* Demonstrates how to connect a master list with a copying details view.
* It builds a JList of Albums with an attached Album details panel
* that presents the current Album selection. The details data
* is copied back and forth from the domain to the details UI components.<p>
*
* A bound variant of this example is the MasterDetailsBoundExample
* that binds the details UI components to the ValueModels provided
* by a details PresentationModel. An even simpler variant is the
* MasterDetailsSelectionInListExample that uses the SelectionInList
* as bean channel for the details PresentationModel.
